If wifi is enabled, then the phone uses it instead of cell networks.

You can check if it is enabled using WifiManager: http://developer.android.com/reference/android/net/wifi/WifiManager.html#isWifiEnabled%28%29 and decide based on that boolean wether you use the network or not.

You can also check getConnectionInfo () to make sure that a connection is active: http://developer.android.com/reference/android/net/wifi/WifiInfo.html
